Because this Seminar is sponsored by SPIE and ASQC, I am assuming there is a broad range of interests represented by the audience. We've tried to orient this paper to cover the interests of both societies. However, because of the nature of our work and interest, this paper is weighted more to user applications for inspection, calibration and problem solving. We hope we have something for everyone. We'll be showing schematics of the various optical accessories and their applications. We'll be looking at the Laser Interferometer interfaced with the calculator for immediate data processing for statistical analysis. With immediate data processing we can easily repeat a measurement for data confirmation should there be some question regarding the results. In some instances, we can interface the calculator to other instruments for data analysis. Again with the calculator on the job - literally -data confirmation is easy.
